Question

(PLEASE UPLOAD ALL PARTS TO THE QUESTION) (IE: PSEUDO CODE AND JAVA CODE TOGETHER NOT ONE OR THE OTHER)

Design an Employee class that fields for the following pieces of information:

1) Employee name

2) Employee number

Next design a class named ProductionWorker that extends the Employee class.

The ProductionWorker class should have fields to hold the following information:

1) Shift number (an integer, such as 1, 2, or 3)

2)Hourly pay

The workday is divided into two shifts day and night. The shift field will hold an integer value representing the shift that the employee works. The day shift is "shift 1" and the night shift is "shift 2". Design the appropriate accessor and mutator methods for each class.

Once you have designed the classes, design a program that creates an object of the ProductionWorker class and prompts the user to enter data for each of the object's fields. Store data in the object and then the object's accessor methods to retrieve it and display it on screen.

Your solution should include:

1. Flowchart

2. Pseudo-code (Gaddis Pseudo-Code)

3. Program Coded (Java Code that is converted from the Pseudo-Code)

4. Program Output

Problem Statement

You should use either inheritance or polymorphism to obtain results in your program.  

Each set of data should be displayed in following form:

Name: John Smith
Employee Number: 12345
Shift: Day
Hourly Pay Rate: $1500

Answer 1

FLOW CHART

///////////////////////////////Pseudo Code//////////////////////////////////////////////

Class Employee
    Private String EmployeeName
    Private int EmployeeNumber
    
    Public Function setEmployeeName(String EmployeeName)
        assign Employee name
    End Function
    
    Public Function setEmployeeNumber(int EmployeeNumber) 
         assign Employee number 
    End Function

    Public Function getEmployeeName()
         return Employee name
    End Function

   Public Function getEmployeeNumber()
        return Employee number
   End Function

End Class

//Similarily for ProductionWorker
Class ProductionWorker
     Private int shiftNumber
     Private int hourlypay
     Public Function setShiftNumber(int shiftnumber) 
        assign shift number
     End Function

     Public Function sethourlypay(int hourlypay)
        assign hourly pay
     End Function

     Public Function getShiftNumber()
        return shift number
     End Function

    Public Function gethourlypay()
       return hourlypay
    End Function
End Class

//User Class
similar to above classes but here object is created as shown
Declare ProductionWorker object
Set object = New ProductionWorker()

////////////////////JAVA CODE TO IMPLEMENT ABOVE PSEUDO CODE/////////////////////////////

import java.util.Scanner;
class Employee{                       //Employee class with atributes employeeName and employeeNumber
   private String employeeName;
   private int employeeNumber;
  
   //accessors
   public String getEmployeeName(){
       return this.employeeName;       // this keyword holds the reference of current object
   }
  
   public int getEmployeeNumber(){

//Designing the user class which uses above classes and its object is created

       Scanner scan = new Scanner(System.in);      //Scanner object for scanning data from user
      
      System.out.println("INPUT");
      
       System.out.print("Enter employee Name ");
       String employeeName=scan.nextLine();       //nextLine() is used to read string with space
      
       System.out.print("Enter employee Number ");
       int employeeNumber=scan.nextInt();       //nextLine() is used to read integer
      
       System.out.print("Enter employee shift Number ");
       int employeeShiftNumber=scan.nextInt();
      
       System.out.print("Enter employee hourly pay ");
       int employeeHourlyPay=scan.nextInt();
  
       //Now the values are set to object properties with the help of mutator
       object.setEmployeeName(employeeName);
       object.setEmployeeNumber(employeeNumber);
       object.setShiftNumber(employeeShiftNumber);
       object.setHourlyPay(employeeHourlyPay);
      
       //Now displaying Employee Data using accessor
       System.out.println("\nOUTPUT");
      
       System.out.println("Name: "+object.getEmployeeName());           //calling accessor to get values
       System.out.println("Employee Number: "+object.getEmployeeNumber());
      
       if(1 == object.getShiftNumber())               //1 = Day and 2=Night Shift
           System.out.println("Shift: Day");
       else
           System.out.println("Shift: Night");
          
       System.out.println("Hourly Pay Rate: $"+object.getHourlyPay());
